A doctor has provided 1 answer

Many things: Red areas like that are often somthing as simple as minor trauma, such as biting your cheek. A simple rule of thumb fir mouth lesions is anything that lasts more than two weeks needs evaluation by your dentist. The great majority of even the persistent lesions are benign but warrant a diagnosis.
